what does lily think is "a better plan" for blacks and whites to get along? how this is kind of contradictory to her next observation?

Lilly thought that everybody becoming colorless would be a better plan. Then, in contrast, Lilly reflects on how special colored women are

They (the Daughters of Mary) didn’t even think of me being different. Up until then I’d thought that white people and colored people getting along was the big aim, but after that I decided everybody being colorless together was a better plan. I thought of that policeman, Eddie Hazelwurst, saying I lowered myself to be in this house of colored women, and for the very life of me I couldn’t understand how it got to be this way, how colored women had become the lowest ones on the totem pole. You only had to look at them to see how special they were, like hidden royalty among us”
